We present the extended electrodynamics in the presence of the axion and darkphoton. We derive the extended versions of Maxwell's equations and darkMaxwell's equations (for both massive and massless dark photons) as well as thewave equations. We discuss the implications of this extended electrodynamicsincluding the enhanced effects in the particle conversions under the externalmagnetic or dark magnetic field. We also discuss the recently reported anomalyin the redshifted 21cm spectrum using the extended electrodynamics.
